Amicrobiologist measures the speed of a swimming bacterium. the bacterium covers a distance of 2.16 microns in 5.0 seconds. the biologist wished to compare the speed of the bacteria with other animals, but the speeds of other animals are listed in kilometers per hour. what is the speed of the bacterium in kilometers per hour? (1 micron = 1 x 10–6 m) use scientific notation and express your answer to the correct number of significant figures. you must show your work for full credit.

Speed of the bacteria,

Step-by-step explanation:

Given that,

Distance covered by the bacterium,

Time taken, t = 5 seconds

We need to find the speed of the bacterium. Mathematically, it is given by :

Since, 1 km = 1000 m

1 hour = 3600 s

v = 0.00000155 km/h

or

So, the speed of the bacteria is . Hence, this is the required solution.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
